Romney camp invokes Hillary Clinton in counterattack TV ad

The latest Democrat the Romney camp is invoking in an effort to discredit President Obama and his campaign is Secretary of State Hillary Clinton, who was Obama's opponent during the 2008 Democratic primary season.

To counter the Obama ads pummeling Romney in the battleground states -- like here and here and here -- Team Romney is now airing an spot that concludes with these words Clinton uttered in '08: "Shame on you, Barack Obama."
